IMPROVEMENT IN ADJUSTABLE NOZZLES F OR HOSE-PIPES.

Specification forming part of Letters Patent No. 177,239, dated May 9, 1876; application filed April 17, 1875.

To all whom it may concern:

Be it known that I, THOMAS HALEY, of

. Gambridgeport, in the county of Middlesex and State of Massachusetts, have invented an Adjustable'Nozzle for Hose-Pipes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specifica- Figure 1 is a perspective view of my adjustable nozzle for hose-pipes. Fig. 2 is a vertical section through thecenter of the same. Fig. 3 is a horizontal section on the line so a: of Fig. 2, the position of the parts being changed; Figs. 4, 5, 6, and 7, details in perspective.

My invention relates to adjustable nozzles for hose-pipes, so constructed as to admit of the diameter of the stream being instantly changed in a convenientmanner without the necessity of shutting off the water; and my invention consists of certain details of construction, hereinafter fully described and claimed.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents the nozzle of a hose-pipe, provided. at its outer end with a screw-thread, a, over which fits a corresponding screW-thread formed on the interior of a flaring mouth-piece, B, which is provided with a flange, b, within which issnugly fitted a ring, 0, having segmental pieces 61 d on its upper side at points diametrically opposite the pieces 61 d, being each cut away on the under side, so as to form guideways for the reception of blocks 6 c, which slide therein, the form of these blocks being such that when brought together a circular aperture, h, will be formed at their center. These blocks 6 c are provided with pinsi i, which project into cam-grooves k k, formed'on the under side of a cap, D, which fits over the flange b of the mouth-piece B, to which it is secured by screws 1, the surface of the cap being fluted to facilitate its being turned by the hand. Through the center of the cap D is formed a circular opening, m, of a diameter corresponding to that of the largest stream required. I

When the pressure of the water is not sufficient to throw a stream of the-larger size (that of the opening m) to the desired height, it is simply necessary to turn the cap D by hand a quarter of a revolution, which causes the cam-grooves k to act on the pins "i, and bring their blocks 6 together, forming the smaller aperture h, previously referred to, thus instantly diminishing the size of the stream, which will, consequently, be forced to a greater distance, no delay being occasioned, as has heretofore been thecase, owing to thenccessity of shutting off the water to admit of the nozzle being removed and replaced by another of different size.

When the cap D is turned to reduce the size of the stream, the blocks e, as they are closed together, are brought down upon the upper end of the nozzle A, the surfaces of the parts in contact being ground, so as to insure tight joints, thus efl'ectually preventing the escape of the water laterally into the cap, and the division of the stream into spray.

When the stream is to be changed from the smaller to the larger size, the cap D is turned back a quarter-revolution, which causes the blocks 0 c to be drawn back out of line with the aperture 122, through which the stream will be projected without obstruction.

What I claim as my invention, and desire to secure by Letters Patent, is

The n'iouth-piece B, the ring 0, WitllitS guideways, the sliding blocks 6 c, with their pins 2' t, and the cap D, with its cam-grooves k k and aperture m, in combination with the nozzle A, all constructed, arranged, and operating as set forth.
